ABSTRACT:
An image editor includes a pixel buffer for storing color data for an image to be edited. A monitor screen displays the image and an active area having a graphic that represents two color descriptor variables. A pair of overlays controls the respective color descriptor variables singly or together. In one embodiment, the active area is a circle with a color wheel about which hue varies angularly and along the radius of which chroma varies. A radial overlay line controls hue and a concentric radially movable ring controls chroma. In another embodiment among others, the active area is a square with a checkerboard graphic. Black and white squares within the checkerboard indicate increasing brightness in the vertically upward direction and increasing contrast in the rightward horizontal direction. Horizontal and vertical hairline overlays control the brightness and contrast, respectively.
